Stuck at CachyOS Grub screen after running Cachy-Update and reboot

Issues & Assistance
1

I apologize in advance if this topic has been solved in another thread. I tried searching for similar reported issues in the forum, but the ones I found don’t specifically mention the error messages that I’m seeing.

I just ran Cachy-Update on my system and after it rebooted I’m stuck at the Grub screen. I don’t get the countdown to load the OS, it just displays the three options:

CachyOS Linux

Advanced options for CachyOS Linux

UEFI Firmware Settings

When I try the first option, I get the following output on the screen:

Loading Linux linux-cachyos …

error: fs/btrfs.c:find_path:1890:file ‘/@boot/vmlinuz-linux-cachyos’ not found.

Loading initial ramdisk …

error: loader/i386/linux.c:grub_cmd_initrd:1082:you need to load the kernel first.

Press any key to continue …

It takes me back to the main Grub screen when I type any key on the keyboard.

There may have been an error installing some packages (maybe Grub) during the update, but I’m not sure. Any ideas on how I can get my system back up and running?

EDIT: I’d like to add that I have a secondary computer (the one I’m typing this on) that is also running CachyOS. I ran the updates using Octopi instead of Cachy-Update on this machine and after reboot, everything loaded normally. I don’t think that made a difference as I assume that both use the same commands to run system updates, but I may be wrong.

Try the Advanced options and boot into the LTS Kernel.

Hi @Oli, I did try that and it showed me the same but with ‘/@boot/vmlinuz-linux-cachyos-lts’ in the first error line.

After shutting down the system for a few mins and starting up cold, it showed the countdown, and then tried to load the OS, but got stuck at the error screen. There was an additional message after typing a key on the keyboard:

Failed to boot both default and fallback entries.

Sound like your update might not have finished properly. Take a Live USB, restore the last snapshot and do the update again. That’s what I would do.

@Oli , I found a “How to restore a Snapper root snapshot on an unbootable system” under FAQ & Tutorials. Is this the guide I should use? I haven’t had to restore a snapshot before. I still have my Live USB created from the March ISO. Should I build a new one with latest ISO?

Looks good. Unfortunately I can’t help you with btrfs, I always use ext4.

Use cachy-chroot from a live usb. In chroot, update and or reinstall your kernels.

Thank you for the tip. I will bookmark that page in case I need to use that in the future.

I followed the guide “How to restore a Snapper root snapshot on an unbootable system” from FAQ & Tutorials step by step and I was able to reboot the system from the last working snapshot, which I believe was generated just before the update.

There are some visual glitches (mainly Gnome Files and Gnome Settings), but it’s working. I’m gonna backup the few documents I have on that computer to an external drive and try running the updates again. Hopefully, I won’t have the same issue. If I do, maybe it’s time to do a fresh install of the OS using the latest ISO. I hope I won’t have to do that, but I’m mentally prepared for the possibility.

I ran the updates via Octopi after backing up my files, and I didn’t see any error messages come up during the process. After reboot, it looks like everything’s back to normal: no problems with Grub at boot; no visual glitches in Gnome Files, Settings and other apps after logging into the Gnome desktop.
